Say what? Postgres isn't dependent on any particular version of glibc;
in fact it runs fine on many Unixen that don't use glibc at all.
How about telling us what your problem is, rather than jumping to a
conclusion about what caused it? What we want to see is exactly what
commands you issued and exactly what error messages you got.
